In the ease of t-he present invention separate control-members which are not connected positively with each other are employed, they preferably being levers, though not necessarily in all instances. The relative independence ot the two controlmembers or levers in respect ot movement secures tor them greater 'Iiexibility and contormability to the conditions and workii'ig ot' the parts which are employed at the two Sides oi the loom. and brings more equally into play, in the protecting` action, the dagger and :frog devices at the two sides ot the loom. Another advantage is mentioned hereinafter.

.frccordingly the invention presents. in a loom, the combination with av moving; lay. protector*mechanism including sluittle-controlled engaging elements moving with the lay, and a warp-guide *with which the warp engages on its way 'from the wa rp-beam.y ot control-members which are not connected positively7 with each other.` located opposite each other laterally ot the loom. and morement-resistin` means combinetfl with the individual control-members adapted to absorb yielding-ly the momentum of the lay in the beatingsup movement and thereby bringr the lay to rest yieldingjly be'liore completion ot such movement, with the individually movable control-members correlated with opposite ends ot the varpguide to produce warp-slacliening movement oi the warpguide.

An illustrative cnibodiment of the invention is shtnvn in the accompanying1 drawings, in which.

By movement ot' the said adjacent shipper-handle 23:2 in one direction, namely 'trom right tole'lt into the position occupied by it in Fig. 2, the shipipier-lever 1T is operated to render the 'friction pulley 13 operative `tor the driving,l ol? thc crank shait and loom g throucfrh the movement of the shipperhandle in the opposite direction, namely trom lett to right. the cflriving is discontinued. A second shipper-handle 39. is mounted upon a roch shaft 341 at the opposite ends ot the loom, tor conrenient use by the weaver when standing` at or near such end, arms upon the two rockshatts 33, fill, being connected by a rod 55 so that the two roclrshalts and shipper-handles turn in unison, and the clutcli-lever 1T may be actu ated by similar movements of either strippern handle.

The parts thus l'ar relerred to are merely iii-iatures ot the loom iu `general.

The drawings show protector-meehanisni comprising as usual a protettoi'ooclrshaft Sill mounted in connection lwith the lay and provided at its opposite ends with preti-eteri'iutrers S2 adapted to be operated on the entrance ot a shuttle into either shuttle-hox to roch the protectorroel shai't 821 in one dillt) rectioni As usual the p rotector-roclrshatt is yieldingly actuated so that the protector tin'- gers tend `normally to approach the interior spaces orn the shi'ttle-boxes. Through' the entrance ot the shuttle into eithershuttlebox action in connection with the correspending protector-finger@ presses the tin-4` gers awa-y trom the spaces lof the shuttle- Vbones so as to rock theprotector#rockshaitV protector-roclcshatt Sill. so that the said engagingv elements 80. 80, constitute shuttlecontrolled engaging elements moving with the lay. -n the present instance thesaid engaginge'lements 80, 80, are in the ftorm ot hooks that are adaptedto engage with hooks 79, 79,upon rods 7S, 78, in connection with the control-members 75, 75. The action corresponds closely with that of usualVV protector-mechanism; namely, whenever a shuttle is fully entered into either shuttle-box the protector-rocks'hait is actuated thereby, the said rockshatt being rocked so as to bring about movement ot both engaging members 80, 80, into positions in which they will not engage with rthe hooks 79, 79,in the upward swinging movement of the lay. lVhen, however, vthe shuttle tails to enter either shuttle-boxatthe end of a flight across the loom, or is not enteredinto one ot the shuttle-boxestar enough Vto operate the corresponding Aprotector-finger 82, the engaging members 80. SO, remain in position to engage with the hooks 79, 79, and in the beating-up movement ot the lay hooks 80, 80, engage with the hooks 79, 79, and as a result ot such engagement draw the rods 7S, 7S in the direction in which the lay is moving` at the time, namely upward.

In this instance the control members 75, 75, are in Athe shape of bell-cranks which are -mounted in connection with the lower parts.

l1, 1l, of the end ramesot the loom. Each bell-crank has connected therewith one eX- tremity ot a powerful spring 76. vBy the tension ot the respective springs 76 the individual-bell-cranlrs are held normally from movement, and by such tension the movementot the lay is opposed as soon as the hooks S()` SO, have taken hold of the hooks 79, 79. One advantage of employing separate control-members at the opposite sides ot a loom is that thereby it is rendered practicable to locate the places ot support tor such members within the diameter ot the heads oit' the warp-beam, as in the drawings, `when the circumstances make such location desirable. This secures greater compactness and in some instances permits a simpler and more advantageous disposition of parts, as well as a less expensive construction, than -when the control-members are fixed upon the opposite ends of a rockshat't .extending across the loom'. Y

For warp-slackening purposes, the warpgiu'de 6l is actuated by the control-levers 75, in the short movement ot thelatte'r.

in unison with the ylay before the beating-up movementof the layV is terminated ybythe resistance offered by the springs, 76. In the present instance'thewarp-guide is' supported by the control-levers through having end-journalsY thereot` entered into: slotted bearings withwhic'h the control-levers are provided. fPreterablyI emp'loy'springs 76,V

In .usual practice the protector-mechanism ,oit agloom is combined and arranged to? throw off .the driving power of the loom and arrest the action ofthe loom when the" protector-mechanismv acts failure ot the Ashuttle to venter properly into one ot the shuttle-boxes. In the case of thel loom that isA partly shown in the drawings, eachrod carries a projection 79a, which,

on ydetection ot as the rod 78 is 4pulledlengthwise upward n as result of the engagement of' the adjacent hook 8O with the hook 79 ot the-rod, is ca'rried againsta tlnger -790 projecting from theV roclishatt 53 or 34 of a shipper-handle 32, the result 'ot which'is rocking of the shipperhandleroclcshatts and movement ot' the shipper-lever 17 by which the drivingY power is thrown off.
